FAQ Frequently Asked Questions

How does this tool determine password strength?
The checker analyzes multiple factors: length, character variety (uppercase, lowercase, numbers, symbols), common patterns, dictionary words, and known weak combinations. It provides real-time feedback and suggests specific improvements to make your password stronger.
Is it safe to enter my real password here?
Yes, your password is completely safe. All analysis happens locally in your browser - no data is sent to servers or stored anywhere. The tool processes your password entirely on your device and never leaves your computer.
What makes a password truly secure in 2025?
Strong passwords should be at least 12 characters long, contain mixed case letters, numbers, and symbols, avoid personal information, and not be reused across sites. Consider using a passphrase with random words, or let a password manager generate unique passwords for each account.
Should I change passwords that show as weak?
Absolutely! Weak passwords are vulnerable to brute force attacks, dictionary attacks, and data breaches. Prioritize changing passwords for important accounts like email, banking, and work systems. Use this tool to verify your new passwords before saving them.
How often should I check my password strength?
Check whenever you create new passwords or update existing ones. Also review your passwords if you have not changed them in over a year, or if any of your accounts have been involved in data breaches. Regular password audits improve your overall security.
